Essential Energy crews focused on repairs in parts of Bemboka, Mogo, Deep Creek, Moruya, Nelligen and Wandella on Tuesday, January 28.
The company restored power to more than 950 South East homes and businesses over the long weekend.
771 properties remain without power across the South East and Snowy Valleys of NSW.
"With weather conditions threatening to deteriorate later in the week, Essential Energy will continue to monitor conditions and plan repair works to ensure the safety of the community and our people," a spokesperson said.
"Essential Energy remains committed to communicating with customers during this time.
"Over the past weeks Essential Energy has contacted the majority of customers remaining without power to discuss their current power arrangements, advise them of estimated power restoration dates and offer the loan of a small portable generator and a fuel voucher for use with their own generators."
The spokesperson said a dedicated team had been deployed to door-knock each of the 87 remaining individual customers who they haden't been able to reach.
"Restoration efforts in the Snowy Valleys are in the final stages with only 32 customers remaining without supply," the spokespersons said.
"Crews will continue to work in the area to progressively restore power to all customers by the end of the week."
